Impressions of the BAT REX


Category: Preamps

I am starting this as a thread instead of a review in hopes others will contribute.
I thought some of you might like to have another take on the BAT REX preamp.
I do think that M. Fremer did a nice and accurate review of the preamp and would refer you to that review for consideration. I have been into this hobby for over 30 years but still do not do well with audiophile catch phrases so please take that into consideration. Of course, we all have our preferences and biases on our way to reproduced musical nirvana and so my listening observations will likewise be biased. I do not participate much but enjoy reading the threads on Audiogon. I admit to being taken aback sometimes when I see others giving dogmatic opinions, e.g. when I read a recent answer by someone I respect and enjoy reading who said that one (equally respected speaker as compared to another) was better “hands down”. Different, yes. Prefer one over another, yes. Hands down” or “no contest”….hmmmm.
So off of my soapbox and on to the REX. I do like BAT preamps and owned a VK51SE before the REX. I did like what the 51SE did in my system and could have continued on with it for many years. The REX, however, is a whole ‘nutter matter, altogether. There are some distinct family resemblances. The control module has the same menu and functions as the 51SE and the appearance is essentially the same- on the outside.
Both modules have nicely engineered fit and finish and give the distinct impression that great care was taken in both design and manufacture. To the sound:
My system is very resolving and sensitive to even minor changes in setup, positioning,
tweaks and equipment both upstream and downstream. With this in mind, the REX is without audible flaw to my ears. I guess I gush as much as others over equipment that produces the positive changes in music that I enjoy hearing and so consider me gushing.
The REX is very, very quiet and my speakers are 108dB efficient. It does dynamics exceptionally well and transient attacks are many times better than the 51SE and at times (good) scary, regardless the type of music. Bloom? in spades. Glare? nada. Soundstaging? top notch. My wife asked me to mute the sound more than once because she thought someone was in the room and she ain’t the paranoid type. Microdetails? hearing things that I would swear were not on the recording, and sorry that I had missed before although a lot credit has to go to the Raven TT and Air Tight PC-1 . Yet, it still comes through on CD’s. Too bright? no way. Evenly balanced across the spectrum? excellent. If there was a couple things that I would have enjoyed more about my 51SE is that it could have just a bit too much lower midrange/upper bass energy and perhaps a little too slow on transients and then release. Not with the REX. Bass authority? authoritative. Sheen over the treble? –No, “sheenless”. Dark? No way- my wife called the sound “rich” and that is her highest compliment and not “rich” as in too much chocolate icing. Pace, rhythm and timing? Now here is where the REX took a giant leap over the 51SE and is just world class IMHO. If it doesn’t have PRAT, I’m probably not going to like it. It does. This machine just got it all right by me. I considered several other preamps, whittled it down to three and bought the REX. Are there other world class preamps out there? Yes! Buyer’s remorse? None. The BAT guys got this one sooooo right. Bullseye. Are there any drawbacks from my perspective? Yes, they will probably come out with a REX II sometime –but I don’t know why. Oh, and a backlit remote would be nice. This one is a keeper.

Hello Inman,

Just wanted to write to say thanks for the good review and that I'm glad you are also enjoying the REX. I've had the REX for over a year now and it still amazes me.

IMO the REX has a unique way with texture that I have not experienced before. It seems to be able to dig deep into the nooks and crannies of the instrument or voice in question that brings out the timbre and texture of tone giving each one their own individual character and vibrant personality. I find this "real" human quality to be uncanny and breathtaking every time I listen to the system.

To me the REX sounds best if you can leave the covers off ( you may want to think twice about this minor tweak if you have precious little chidren or pets ) both units and benefits from vibration isolation. I recently switched from a Zoethecus rack to the Finite Elemente MR rack that the REX and my digital front end sits on and got a nice step up in performance. I also found the Nordost Valhalla PC works extremely well with the REX in the context of my system.

Like the reviews in Stereophile and Absolute Sound and for the same sonic reasons ( but certainly not to the degree ) I also have found the AC shunt regulation switch sounds best set and positioned for the 6C45's rather then the 6H30's.

Thanks again Inman for posting and I wish all the enjoyment and joy I have from ownership of this incredible preamp.

All the best,

Tom
Hello John,

As you know I recently made a significant upgrade elsewhere in my system. This upgrade has made me have an even deeper appreciation for the REX. It's simply the most natural sounding electronic component I've ever heard.

If it means anything to you one way or the other, I also have been fortunate enough to have made a living as a professional musician for 35 years of my 51 years of life. Mostly playing live, a fair amount of studio work and teaching, and I LOVE listening to music. Other musician friends who have come by for a listen are also astounded by the unique natural portrayal of the REX's texture/timbre of tone, so much so that it stops them in their tracks, and the reaction is ..... wow! Things just sound so undeniable "right" with the REX.

John, please know I wish you all the best in finding a pre-amp that you feel the same way about.

Enjoy,
Tom
Hi Guys,

BAT is making my pair of REX Power mono-blocks amps for me as I type!!! I'll be sure to keep you informed.

Enjoy,
Tom
